the pin and later restoring it so that the fact 7 that access has been had is concealed.

The present invention has for its object to provide a hasp that does away with hinge pins and forms the hinge connections from the plates themselves, andin such manner that access to the cupboard or otherplace cannot be obtained without leaving noticeable traces on the hasp, and moreover, a hasp of this kind whose hinge parts are ofl'setso that no deformation of the surface is necessary for attachment. a

In the drawings, which represent one suitable embodiment of the invention, Fig. 1 is an elevation with the hasp open Fig. 2 is a similar elevation with the hasp closed; Fig. 3 is an end elevation of the hinge end of the hasp base; Fig.4 is a similar view of the hinge end of the hasp plate; and Fig. 5 is a sectional plan view on the line 55, Fig. 2. While the hasp is suitable for use in any place where two parts are to be locked together or released, such as a door to its casing or the like, the drawings for convenience show the invention applied to two adjacent garage doors 1, 2, both of which may be assumed to swing. The hasp set includes two members which are respectively attached to the two doors or other parts. The first is the staple member, which includes a suitable base plate 3 carrying the staple 4, which is of loop form with its ends passing through openings 192s. Serial No. 277,575.

securing means, such as the bolts or screws 6. The second jmember, is the hasp, which likewise includes a base or body plate 7. at-

tached to the other; door member 1 in any.

suitable manner, such as by the bolts or screws 8, and to one end of which is pivotally connected the hasp plate 9. The hinge connection is at the opposite edge of the base plate 7 from the staple plate 3, so that when the hasp is swung over to locked position with its recess 10 slipped over the staple 4, said plate covers and prevents access to the securing devices, 6, 8 of both plates, as is usual.

The hinge connection between the hasp plate 9 and its base plate 7 is formed of the metal of said plates, by lacing them together as it were, thereby avoiding use of any hinge pin. Moreover, the end edge portions of the two plates are ofiset or bent outwardly from I the planes of the plates, as shown more partucularly in Fig. 5. As a result, the hinge connection produces no projection of the parts beyond the rear surface of the base plate 7 and it may be attached directly to the fiat surface of a door without forming a recess to receive the hinge connection. One of the parts 7 or 9 is formedwith end extensions 11, two being shown, beyond its offset edge portion 12, the extensions being rolled to form eyes, with the turns of said eyes passing through recesses 13 in the offset portion of the base plate 7. The arrangement is such that the metal of each eye is rolled back upon itself practically into abutting relation directly to thefiat surface of the door by any i 1 with the offset plate portion 12, as indicated at 14, Fig. 5, so that in closed position of the hasp the free end edge of each loop is contained within the recess in the base plate 7. It is therefore protected against any access thereto of a splitting or prying tool, such as a chisel or screwdriver. In the swinging motion of the hasp, of course, it turns freely upon the metal bridges 15 of plate 7 opposite eachof the recesses therein, which bridges. therefore "serve as the hinge pin.

With this hasp it is impossible to take off the hasp plate without severing the eyes 11 or cutting through the bridges 15, either of which operations is at best a difficult task and inevitably leaves noticeable traces of its occurrence.

What I claim is:

A hasp of the character described, comprising a base plate adapted for application of one of its faces toa supporting surface and at one "end having laterally slotted and ofiset angularly away from said face toform a hinge bridge spaced therefrom, .and .a staple receivin plate having one end correspondingly o set and bent'into eye form embracing said hinge bridge, the free end of said eye entering said slot on the same side of the base plate as its said surifiace, whereby a-in locked position of the hasp the free end of said eye is concealed and inaccessible beneafth "the 'ofi'set "ends of said plates. In testimony whereof I hereby aflix my signature.
